Irish surgeons have pioneered the institution of laparoscopic lavage for acute non-faeculant diverticulitis. The operative method described involves laparoscopy, copious washout, drain placement and treatment with antimicrobial therapy (intravenous for 72hours followed by oral for one week). Benefits include low mortality, stoma avoidance, minimal wound infection, shorter operative time and no difference in recurrence when compared to primary resection and anastomosis. Having demonstrated a clear clinical advantage of laparoscopic lavage over standard of care (Hartmann's procedure or primary resection and anastomosis) for acute non faeculant perforated diverticulitis, we feel the time is ripe to formalise these findings through performance of a multicentre national randomised controlled trial- LapLAND (LAParoscopic Lavage for Acute Non-faeculant Diverticulitis).
